The 1880 80/79 Morgan Dollar is worth anywhere from $35 in heavily worn condition to well over $500 or more in higher mint state grades — and certain certified examples have sold for thousands at auction. If you’ve come across one of these silver dollars in an old collection or family heirloom box, you may be holding something quite special.
This coin belongs to a fascinating category called “overdate” varieties, where a die originally engraved with one year was repunched with a new date. On the 1880 80/79 Morgan Dollar, you can actually see traces of the “79” beneath the “80” on the obverse. It takes a good magnifying glass to spot, but once you see it, there’s no mistaking it. If you want a quick way to identify what you have, a coin identifier and value app can help you scan the coin and match it to known varieties in seconds.
What Makes the 1880 80/79 Morgan Dollar Special
The Morgan Dollar series, struck from 1878 to 1904 and again in 1921, is one of the most popular coin series among collectors. The 1880-dated Morgans in particular include several fascinating varieties because the Mint was transitioning dies and reusing older equipment. The 80/79 overdate variety exists across multiple mint marks — Philadelphia (no mint mark), San Francisco (S), and New Orleans (O) — each with its own collector following and value range.

The overdate effect happened when engravers at the U.S. Mint repunched a new date over an existing 1879-dated die. This wasn’t unusual in the 19th century. But for collectors today, it creates a visually distinct variety that commands a premium over regular 1880 Morgan Dollars.

The rarity of a clearly visible overdate, combined with the already strong demand for Morgan Dollars, is exactly why this coin is worth knowing about. Even a coin in average circulated condition is more valuable than most people expect.

How to Identify the 80/79 Overdate on Your Coin
Spotting the overdate is key to knowing whether your coin is a standard 1880 Morgan or the more valuable variety. You’ll want a 10x loupe or a strong magnifying glass. Focus on the “8” and “0” in the date. On the 80/79 overdate, look carefully beneath the “8” — you should see the remnants of the lower loops of a “7” peeking through. The “9” beneath the final “0” can also be visible on well-struck examples.

It helps to examine the coin under a raking light at an angle, which brings out the die details more clearly. Don’t clean the coin. Cleaning reduces value significantly and can make die details harder to read.
If you’re unsure what you have, CoinKnow is a handy tool that lets you photograph your coin and cross-reference it against a comprehensive variety database. Many everyday collectors have discovered valuable overdate varieties exactly this way — coins sitting unrecognized in old boxes for decades.
Should You Get It Graded or Sell It As Is
If your 1880 80/79 Morgan Dollar appears to be in uncirculated or near-uncirculated condition, professional grading from PCGS or NGC is usually worth the investment. A certified MS-63 or better coin with the 80/79 variety designation on the label can sell for significantly more than a raw (ungraded) coin of the same quality.

For worn circulated examples, the grading fees may exceed the benefit unless the coin is in the EF-40 range or better. Dealers and auction houses will make offers based on their own assessment of grade.

FAQ
Q: How do I know if my 1880 Morgan Dollar is the 80/79 overdate variety?
A: Use a 10x magnifying loupe and examine the date closely. Look for traces of a “7” beneath the first “8” and a “9” beneath the final “0.” The overdate details are usually visible on well-struck coins. Apps like CoinKnow can also help you cross-check the variety.
Q: Is the 1880 80/79 Morgan Dollar rare?
A: It’s not extremely rare in circulated grades, but it is a recognized variety that commands a consistent premium over regular 1880 Morgans. In high mint state grades (MS-65 and above), examples become genuinely scarce and can bring strong prices at auction.
Q: Does the mint mark affect the value of the 1880 80/79 Morgan Dollar?
A: Yes. San Francisco (S) and New Orleans (O) examples in higher grades often carry slightly higher premiums than Philadelphia coins, partly due to collector demand and strike quality differences. Always check the reverse of the coin — the mint mark appears just above the “DO” in “DOLLAR.”
